Which marine friend knows about Bunsen valves? Could you explain the principle? Thank you.
The method of manufacturing a Bunsen valve involves inserting a glass tube with a short section of rubber tube attached to it into the plug; there is a narrow slit on the side of the rubber tube, and the other end of this tube is connected to a glass rod, so that gas can escape while air cannot get in). The plug is then used to seal it
